Memory Test

To run a memory test:

Boot from UBCD5 (CD or USB flash drive)
Using the arrow keys, scroll down to "Memory" and press Enter
Using the arrow keys, scroll down to "Memtest86+ V5.01" and press Enter
Allow Memtest86+ to run though at least 1 full pass (2 or 3 passes would be preferred)
You should see ZERO errors
If there are errors, shut down the computer, remove all but 1 memory module, and run Memtest86+ again.
Repeat for each memory module to determine which one(s) are defective.

Hard Drive Test

To run a hard drive test:

Determine your hard drive's manufacturer:
- In Windows, look in Device Manager - Disk Drives
- In the BIOS, look for IDE or SATA drives (varies by motherboard)
- Open up the computer case and look at the sticker on the drive

Seagate drive model numbers start with "ST"
Western Digital drive model numbers start with "WD"
If the model number does not start with "ST" or "WD", post it to the forum

Boot from UBCD5 (CD or USB flash drive)
Using the arrow keys, scroll down to "HDD" and press Enter
Using the arrow keys, scroll down to "Diagnosis" and press Enter

For Seagate drives, use the arrow keys to scroll down to "Seatools for DOS V2.23" and press Enter
For Western Digital drives, use the arrow keys to scroll down to "Data Lifeguard Diagnostic for DOS V5.22" and press Enter

Run the short/quick test first.
If the short/quick test fails, replace the hard drive.
If the short/quick test passes, run the long/extended test.
If the long/extended test fails, replace the hard drive.

*If the hard drive is not detected by Seatools or DLG Diags, it could be because the storage controller is set to AHCI mode in the BIOS.
To resolve this, boot into the BIOS and set the storage controller mode to IDE or SATA. (varies by motherboard)
Boot from UBCD5 again and run the hard drive diagnostics.
After you finish running the diagnostics, boot into the BIOS again and set the storage controller mode back to AHCI.
